Abstract
Tropical theileriosis, caused by the tick-transmitted apicomplexan parasite Theileria annulata, remains a major constraint on cattle production across North Africa, the Mediterranean basin, the Middle East and South Asia. Current control depends on acaricides, the theilericidal drug buparvaquone and live attenuated schizont vaccines, but acaricide resistance, buparvaquone-resistance mutations and the logistical demands of vaccination are eroding the sustainability of these tools. Host genetics offers a complementary and durable alternative. Indigenous Bos indicus breeds are consistently more resistant to ticks and tolerate T. annulata infection better than exotic Bos taurus cattle, and this advantage has a measurable heritable component. Unlike previous reviews, which treat tick resistance, T. annulata immunobiology and livestock genomic selection as separate subjects, we integrate all three and assess host genetics specifically against the failure modes of current control. We review the tick, parasite and host interface, the evidence for natural resistance, and the genetic and immunological mechanisms involved, including signal-regulatory protein, bovine major histocompatibility complex class II and inflammatory pathway genes. We then assess whether genomic selection, multi-omics, machine learning and gene editing can translate these mechanisms into resistant cattle, and we weigh the biological, economic and infrastructural barriers to implementation. The evidence indicates that host genetics will not replace existing control but could reduce reliance on acaricides and chemotherapy. That contribution remains prospective rather than demonstrated: no resistance marker for T. annulata has yet been validated, prediction accuracies are moderate and transfer poorly between breeds, and no endemic production system has implemented selection for resistance.
It is concluded that bridging the gap between foundational CRISPR research and its real-world applications is imperative and future efforts should focus on democratizing tools via open-source platforms, advancing delivery systems, and fostering sustainable innovation through synthetic biology integration to fully realize the transformative potential of genome editing in organisms beyond model organisms.

It is argued that formation of a tumour-intrinsic niche is a prerequisite for BRAF-mutant CRC seeding to distant organs and that interference with niche formation may help avoid metastatic relapse.

Genetic engineering (GE) and gene editing may endow traits to trees such as increased biomass and the production of novel biomaterials. Long-lived organisms such as trees might be subject to biotechnology-related risks that could be different than those of annual row crops. Those risks could be relevant to production in engineered plantations and beyond plantations to natural forests. Therefore, appropriate risk regulation is important to assure biosafety of commercialized engineered trees. In addition to gene flow via sexual reproduction, vegetative reproduction might play an additional role in environmental "exposure" risk relative to transgene dispersal in GE tree plantations. While vegetative reproduction is beneficial for preserving desired genetic traits during tree propagation, it may lead to proximal clonal spread in the field. Although the environmental risks associated with vegetative reproduction of GE trees are recognized in commercial forestry, there are few field-based environmental risk assessment (ERA) studies on dispersal risks of self-propagated GE trees. GE or gene editing of target genes involved in the vegetative propagation processes may be useful to mitigate environmental risks of clonal spread through vegetative reproduction. This review provides updates for recent field test results of GE and gene edited trees. Gene candidates related to vegetative reproduction including adventitious shooting (AS) and adventitious rooting (AR) are discussed herein as a means to mitigate unintended clonal spread from GE tree plantations.
The central nervous system (CNS) harbors a distinct immune memory programming system, wherein immunogenic cell death (ICD) acts as a pivotal signaling hub. A spectrum of insults, from systemic metabolic dysfunction to local protein aggregation and ionic dyshomeostasis, can provoke ICD in neurons, glia, and resident immune cells. This process orchestrates the release of damage-associated molecular patterns (DAMPs) from distinct subcellular compartments. These DAMPs synergistically initiate both innate trained immunity (TI), characterized by profound metabolic-epigenetic reprogramming, and antigen-specific adaptive immune responses that traverse the blood-brain barrier. Together, these pathways constitute an integral network of central immune surveillance. Crucially, this ICD-driven immune programming exhibits a striking functional dichotomy depending on the pathological context. In non-neoplastic conditions such as neural injury and neurodegenerative diseases, uncontrolled ICD signaling can establish a pathological trained immune memory, driving a self-perpetuating cycle of chronic neuroinflammation and tissue damage. Conversely, within the tumor microenvironment of malignancies like glioma, the adaptive immune responses elicited by ICD are frequently subverted by potent immunosuppressive mechanisms, culminating in tumor immune escape. This review dissects the differential regulatory mechanisms of ICD-mediated immune memory in CNS tumors versus non-tumor diseases. We aim to elucidate the molecular switches that govern the transition of this immune program from a beneficial, compensatory state to a pathological, detrimental phenotype. By exploring emerging therapeutic strategies, including gene editing, nanomaterials, and bioactive phytochemicals that precisely target ICD pathways, we provide a theoretical framework for understanding CNS immune homeostasis and for the rational design of precision immunotherapies.
